API Testing Made Effortless : KushoAI

有没有想过为什么我们使用研磨机，而我们的祖先却徒手进行所有研磨？增强的技术帮助我们超越了上一代，实现了日常工作的自动化，这使我们能够更多地关注生活的其他方面，从而带来更多的发现。与当今的工程师坐下来几个小时试图处理 API 调用中传递的所有信息不同，您希望提高工作效率并更多地关注处理数据以将一些有用的代码融入现实生活中公用设施。

作为一名后端工程师，我理解没有完全掌握 API 端点服务器如何运作的困难 - 或者更准确地说，没有完全理解（？）我们的 API 端点服务器如何运作的挫败感。此外，了解 API 端点的最佳性能和测试运行时环境一致成为工程师的首要任务。因此，我们测试 API 的方式最终决定了我们的速度、准确性以及我们在代码早期发现错误的能力。

当思考为什么我们需要测试我们的 API 时，您的脑海中可能会出现许多问题！尽管测试驱动开发看起来很简单，但它是开发人员可能经历的最困难和最顽皮的生命周期之一。最终，我们测试路由和处理程序的方式决定了我们的数据管理生命周期的进行方式。这就是KushoAI出现的时候。

说实话，我在发现可以帮助简化我的开发周期的人工智能代理时偶然想到了KushoAI，我向你保证。 “测试我的工具时，后端工程师的生活从未如此简单”。但 KushoAI 到底是什么？这只是“那些被过度炒作的”人工智能工具，只是存在吗？它真的有用吗？如果是，那么如何？最重要的问题是：“是什么让 KushoAI 优于其他 AI 测试代理”。这就是为什么我决定创建一个博客来帮助您了解 KushoAI 的工作原理以及它提供的功能，这使得它与其他人不同！！

好吧，按照他们的文档中定义的书本定义：“KushoAI是一个用于API测试的AI代理，它为您的API生成详尽的测试套件 在几分钟内 – 您需要做的就是输入您的 API 信息，然后坐下来，让 KushoAI 找出您的 API 在生产中可能出现的实际场景，并为它们编写准备执行的测试。 ”

简单地说，您决定如何将输入提供给代理，并收到详细且独特的测试套件，它检查您的 API 将如何运行。是这样吗？显然不是，这就是为什么我在这里花时间写关于这个工具的博客。让我们看看 KushoAI 为工程师提供的最独特的功能。

测试套件创建

（在 KushoAI 中创建测试套件的不同方法）

因此，该平台提供的第一个也是最令人兴奋的功能是为 API 选择数据输入以创建测试套件的多样性。 KushoAI 的文档指定：

“测试套件是 KushoAI 为您的 API 生成的测试集合。从高层次来看，这就是 KushoAI 上测试生成的工作原理：

• 您提供 API 信息以使用下面指定的格式之一创建测试套件。
• KushoAI 会查看您的 API 信息并找出此类 API 可能出现的问题。
• 根据这些信息，KushoAI 提出了测试（包括场景和执行测试所需的 API 负载），这些测试将在该 API 的测试套件中提供。”

KushoAI 提供了 4 种主要方法来帮助您为测试生成提供 API 输入：

1. 手动输入API详细信息
2. 导入 OpenAPI 规范
3. 导入邮递员收藏
4. 复制并粘贴 cURL 命令

在这4种方法中，我最喜欢的方法一直是导入邮递员收藏。不过，我想一一简单描述一下所有方法：

a) Manually Enter API Details

This is by far one of the most utilized methods on the platform due to its simplicity and ease of understanding. All you need to know is how your API endpoint was designed, including the Endpoint URL, Headers, Path Params, Query Parameters, and the Request Body for your specific API request. Once you enter this information, all that's left to do is click "Generate," and BOOM!! In just a couple of minutes, your API tests are generated.

Now, a common question might be: what exactly are these parameters if you're unfamiliar with the terms? Don’t worry—KushoAI has got you covered. The platform provides clear explanations of what these parameters are, using dummy API examples for easy understanding. Additionally, KushoAI offers a feature to create Groups of API suites, similar to how Collections work in Postman.

b) Import OpenAPI Specs

Once in our life we all have used services like Swagger for our API. If you already have your API hosted on Swagger, it is probably the best idea to directly import your JSON into KushoAI, which then utilizes an internal parser to obtain all information about your API and all endpoints as listed in your JSON. In addition KushoAI also provides you an option to select only those endpoints which you want to test. What lies next is to review the Endpoint URL and you are good to go. Just click Generate and site back to relax while KushoAI does all the work for you. A visual representation of how this works is shown below :

c) Import from Postman Collections

One of my favorite features is the ability to import from Postman Collections, largely due to my extensive use of Postman. Previously, I would manually input the endpoint with the necessary methods and parameters. However, what I really wanted was to integrate these API calls directly into my tests, which is how I discovered KushoAI.

Here’s how simple it is:

1. Export your Postman Collection as a JSON file.
2. Upload the JSON file to KushoAI.
3. Just like when importing OpenAPI specs, select the required parameters for which you need to generate tests.
4. If you have any optional parameters like auth tokens, requests etc, then enter the details in the next popup.
5. Click "Generate," then sit back, relax, and let KushoAI work its magic.

d) Import using cURL command

KushoAI also provides you an option to import the curl commands and directly create tests for you. A simple example of real world applicable cRUL command for which tests were created is given below.

curl -v -X POST \
    -F 'hostname=docker' \
    -F 'modelid=5000000002' \
    -F 'sitegroupid=1' \
    -F 'siteid=772' \
    -F 'sitename=Niwot Ridge Forest/LTER NWT1 (US-NR1)' \
    -F 'pft[]=temperate.coniferous' \
    -F 'start=2004/01/01' \
    -F 'end=2004/12/31' \
    -F 'input_met=5000000005' \
    -F 'email=' \
    -F 'notes=' \
    'http://pecan.localhost/pecan/04-runpecan.php'

KushoAI Workbench and API Information

KushoAI makes accessing and managing API information incredibly simple, providing insights into data such as filters, counts, and detailed API information. Once KushoAI has processed your API details, it typically takes no more than a couple of minutes to generate fully functional test suites for your API collection, ready for execution.

But what if you need to fine-tune the generated test cases to fit specific scenarios? No worries—KushoAI has you covered with an easy-to-use interface that allows you to modify request details and tailor the tests to your exact needs.

In addition to customization, KushoAI offers parallel computation and API calls, a feature that significantly reduces latency and boosts efficiency. This is one of the most impressive features KushoAI brings to the table, allowing you to test APIs faster and with greater precision.

However, when I say "one of the most impressive," I truly mean it, because KushoAI offers even more. You can automatically generate AI Assertions for each API request using Generative AI, which, in my opinion, is the standout feature of the platform. You can even integrate custom assertions, a feature that I haven’t seen work as quickly or effectively anywhere else.

Below are some examples of requests I processed using KushoAI, demonstrating how its services work. For this, I used a custom endpoint for the WeatherAPI to showcase KushoAI’s capabilities. The ability to easily integrate with your own custom assertions is a game-changer, offering unmatched flexibility and speed. Below are some assertions which were automatically generated using KushoAI's inbuilt Generative AI :

expect(response.response.location.name, "name should exist").to.exist;
expect(response.response.location.name, "name should be a string").to.be.a('string');
expect(response.response.location.region, "region should exist").to.exist;
expect(response.response.forecast.forecastday[0].hour[0].gust_kph, "gust_kph should be a number").to.be.a('number');
expect(response.response.forecast.forecastday[0].hour[0].uv, "uv should exist").to.exist;
expect(response.response.forecast.forecastday[0].hour[0].uv, "uv should be a number").to.be.a('number');
expect(response.statusCode, "statusCode should exist").to.exist;
expect(response.statusCode, "statusCode should be a number").to.be.a('number');

Workspaces and Collaboration

KushoAI offers a robust Workspaces feature that enables seamless collaboration among users, allowing teams to work together efficiently on API collections. This feature is especially useful for larger teams or projects where multiple individuals need to contribute to the same API testing suite, fostering real-time collaboration and making the development process smoother.

If you're familiar with GitHub, you'll find this functionality quite similar. Just as GitHub allows multiple developers to collaborate on code, KushoAI enables teams to work simultaneously on API collections, share test cases, and address the same issues without stepping on each other’s toes.

This Spectacular feature helps teams stay in sync, reducing bottlenecks and improving productivity. By centralizing the workspace and offering easy access to shared projects, KushoAI streamlines the API testing workflow, making it easier for users to track changes, provide feedback, and enhance the overall quality of their API services.

Whether you're working with a small team or managing a large project with many contributors, KushoAI ensures that collaboration is as efficient and frictionless as possible. With real-time updates and shared access to API collections, it takes teamwork in API testing to a whole new level. You can also manage your API Keys for further integrations and CI automation (which we will discuss a bit later) along with Environment Variables to store your secrets.

KushoAI's Workbench provides a more sophisticated and user-friendly interface than Postman's, allowing for greater flexibility and control during API testing. While Postman is well-known for its simplicity and ease of use, KushoAI goes above and beyond with capabilities such as custom test case generation, real-time modification of API requests, and parallel test execution, all of which greatly speed up the testing process. KushoAI's Workbench is built with Generative AI at its heart, allowing it to automatically develop extensive test cases across numerous scenarios—something Postman often restricts to simple checks like response status and time. Furthermore, KushoAI delivers extensive insights into the data coming via your APIs, allowing users to select and analyse results more accurately.

Integration in your CI/CD Pipelines

KushoAI offers seamless integration with your CI/CD pipelines, providing automated, real-time test generation and execution, without the need for any manual intervention. This integration ensures that every time a new commit is pushed or a change is made, KushoAI automatically runs tests to validate your API’s functionality, performance, and security.

Currently available as part of KushoAI’s Enterprise plan, this feature is designed for organizations that need continuous testing at scale. By incorporating KushoAI into your CI/CD workflow, you can ensure that every API update is thoroughly tested, reducing the likelihood of bugs and security vulnerabilities slipping into production.

KushoAI also supports GitHub Actions, making it easy to integrate API testing directly into your GitHub-based workflows. This allows your development and testing teams to catch issues early in the development process, improving overall efficiency and reducing the time spent on manual testing.

Automating your API testing as part of a CI/CD pipeline not only enhances testing performance but also significantly boosts security. Every change is automatically validated, meaning you can deploy confidently knowing your APIs have been tested at every stage of the development lifecycle. This eliminates potential security risks caused by human error, offering a reliable safeguard against bugs and vulnerabilities.

For more detailed information or to discuss how CI/CD integration can benefit your organization, the KushoAI team is available to provide consultation and support. Below is a visual representation of how the integration works within a typical pipeline:

Test Reports.

Once your test suites are completed, KushoAI will notify you when the testing process is complete, allowing you to focus on other things without having to manually monitor the tests. This is especially valuable for teams with many priorities, since it guarantees that your time is used efficiently while KushoAI does the testing.

In addition to alerts, KushoAI offers a real-time view of your test suite's generation status. You can simply follow the progress of your tests via the generation status page on the home tab, which keeps you updated on every stage of the process. This real-time visibility is critical for ensuring that no tests are left unfinished, providing you assurance that all APIs have been completely tested.

Once testing is completed, KushoAI provides export choices for test suites and results. You may export these reports in 'HTML' format, which provides a concise and well-organised overview of your test findings. These reports not only capture current tests, but they may also be saved for future reference, making it easier to follow progress or regression issues over time.

This functionality is extremely useful for companies trying to continually enhance their API speed. Reviewing these extensive reports allows you to discover possible issues, make appropriate changes, and retain a historical record of how your APIs have changed. KushoAI's reporting tools guarantee you always have access to actionable insights.

KushoAI's end-to-end testing (beta) features

Through the use of KushoAI's End-to-End (E2E) testing functionality, developers may replicate real-world processes by sequentially testing numerous API interactions to make sure they perform as intended. Engineers may use this functionality to cover complicated situations involving several endpoints, offering insights into the behaviour of your APIs in production environments. E2E testing offers many features, some of the most prominent features are:

1. API Selection for Testing: - Users can add new APIs or pick existing ones to the test suite. For example, selecting "Weather Forecast API for Gorakhpur" as displayed in the image demonstrates that several endpoints and functions may be coupled to replicate a real-world scenario.

2. Workflow Automation: - The "Run" and "Save Workflow" buttons enable users to develop, run, and store end-to-end tests for reuse. You may create processes that test APIs in the same order in which a real user would interact with them.

3. Collaboration and Customization: - The Workspace feature in the top-right corner helps teams cooperate on processes and maintain test environments efficiently.

4. User-Friendly Interface: The UI is intended to provide straightforward API administration, allowing users to quickly switch between adding new APIs and selecting pre-configured ones for testing. It also supports parallel API execution and real-time scenario validation.

KushoAI vs. Postman: Generative Tests

One might wonder, why choose KushoAI when Postman also offers generative tests? The answer is simple: KushoAI offers a far more comprehensive and intelligent testing experience. While Postman generates tests based on limited factors like response time and status codes, KushoAI generates tests across all possible testing scenarios, regardless of the specifics of your collection.

This is a game-changer. Postman often restricts the scope of its generated tests, relying heavily on predefined conditions. In contrast, KushoAI takes a more robust approach, ensuring that your API is tested under a broader array of conditions, including edge cases and performance bottlenecks that Postman might overlook.

To illustrate this, I ran simulations on my localhost backend server to check user data and responses similar to the earlier example using the Weather API. The results clearly show that KushoAI's generative testing framework not only provided more test cases but also delved deeper into potential failure points and error scenarios that Postman's approach missed entirely. KushoAI's ability to create comprehensive tests across all layers of functionality, from endpoint stability to data integrity, demonstrates its superior coverage and reliability.

Moreover, KushoAI's Generative AI is tailored to identify nuanced issues in your APIs, offering intelligent assertions and custom test cases that align with your specific needs—something Postman lacks. With KushoAI, you're not just testing based on surface-level metrics; you're validating the entire API lifecycle, from security vulnerabilities to real-world stress testing.

In short, KushoAI outperforms other generative testing solutions like Postman by ensuring that every aspect of your API is rigorously tested, offering deeper insights, greater flexibility, and more reliable results. The proof is in the tests generated via Postman and KushoAI which showcases how KushoAI’s advanced testing engine gives you a level of coverage that sets it apart from the competition.

While KushoAI decides to test scenarios comprising of data conditions, Postman decided to test scenarios with Error codes and Body Content.
